Research & Evidence
Artificial intelligence-derived ECG-age identifies higher stroke risk in intermediate-risk atrial fibrillation.
Journal article
Among 832 anticoagulation-naive patients with atrial fibrillation and a CHA₂DS₂-VA score of 1, replacing age with artificial intelligence-derived ECG-age identified a higher-risk subgroup. An EA-CHA₂DS₂-VA score of at least 2 was associated with higher stroke/TIA risk (HR 1.82) than scores below 2. Prospective studies are essential before clinical integration. [1]
Diagnostics & Pathology
Machine learning identified GBM as top predictor of mortality in acute stroke using TyG and LDL-C.
Journal article
In a multi-center cohort of 3,028 MIMIC and 2,385 eICU patients, Boruta and LASSO selected features for ten machine learning models, with SHAP for interpretation; among multivariable models incorporating nine selected predictors, GBM achieved the best performance (AUC = 0.802) for predicting mortality. [4]
Operations & Workflow
Nurses spend up to 30 % of shift on documentation, reducing patient contact.
Podcast from Lifers (Second Opinion)
The interview reports an Intermountain time‑motion study showing bedside nurses may devote as much as thirty percent of a shift to documentation—about three hours of a twelve‑hour shift not spent with patients. Documentation is described as quick, repetitive clicks that detract from the relational nature of nursing work. [2]
Policy & Governance
Liability for autonomous AI in healthcare should fall on developers, not clinicians.
Podcast from AI and Healthcare
The interview describes Ezekiel Emanuel's view that developers should bear liability for AI medical tools, citing their deep pockets and role in creating the systems, and argues that proper legislation can make liability a solvable issue rather than a barrier to adoption. [3]
